ALBERT B. HOLLEY AND JOHN A GAVIN, OF VIRGINIA, MINNESOTA, ASSIGNORS, BYDIREPT AND MESNE ASSIGNMENTS, TO SAID ALBERT B. HOLLEY,

ATTACHMENT FOR BADIATORS.

Application filed June 30, 1922. serial l o. 571,894.-

To all whom it may concern.

Be it known that we, ALBERT B. HOLLEY and JOHN A. GAVIN, citizens of theUnited States of America, residing at Virginia, in the county of St.Louis and State of Minnesota, have invented certain new and usefulImprovements in Attachments for Radiators, of which the following is aspecification.

Our present invention relates generally to attachments for radiators,and more articularly to bushings whereby without the use of valves,required quantities of steam may be furnished steam radiators, ourobject being the provision of a device of this nature by the use ofwhich hot water and other house heating radiators may beconverted to theuse of steam and the bushing regulated when fitted to the radiator so asto supply the desired and proper amount of steam without the use ofsupply regulating valves and in such manner as to prevent.

unwarranted tampering with the steam supply.

The invention is especially applicable in apartment houses and the likefor these reasons and is not only inexpensive in first cost but ispractically without expense as far as upkeep is concerned and ispeculiarly and uniformly effective for the intended purposes.

In the accompanying drawing which illustrates our present invention andforms a part of this specification,

Figure 1 is an end view of a steam radiator showing our improved bushingapplied thereto, s

Figure 2 is a vertical. longitudinal section therethrough,

Figure 3 is a vertical longitudinal section through a hot water radiatorshowing our invention adapted thereto,

Figure 4 is an end view of the bushing looking at the inner end thereof,

Figure 5 is an enlarged end view looking at the outer end of thebushing, and

Figure 6 is a central longitudinal section through the bushing shown inFigure 5.

Referring now to these figures our invention proposes a bushing whichmay be applied to either a steam radiator such as shown at 10 in Figures1 and 2 or a hot water radiator such as shown at 11 in Figure 3, thebushing being connected in Fig- I ures 1 and 2 to the lower portion ofthe end coil while in the case of the water radiator bushing is in placealthoug capable of re- 4 moving should a change be thereafter required.

In presenting this metering radiator bush-. ing capable of avoiding thenecessity of supply regulating valves, our invention proposes a bushinghaving a generally cylindrical chambered or hollow body 12, provided atits outer end with an external wrench engaging surface as for instancein the nature of a polygonal flange 13 and provided with externalthreads 14 adjacent to the flange to engage threads within the bushingreccivin bore of a radiator.

The chain er of the bushing is best seen at 15 in Figure 6, it beingnoted that the outer end of the bushing has an internally threadedsupply pipe receiving bore 16 extending centrally therethrough and incom munication with the chamber 15 and that the inner portion or end ofthe bushing has either a single opening or an annular series of openingsradiating from the inner portion of the chamber and thus located in thatportion of the bushing which when properly fixed within a radiator 10,11, isdisposed within its steam receiving space of the radiator.

There an annular series of openings 17, 18, 19, 20, 21 and 22, areemployed, the are raduated as to cross section aroun the ushing, eachleading from the chamber of the bushin and each being closed at itsouter end a small screw or other plug 23 so that it becomes apparentthat it is simply necessary in every instance to determine the size ofsupply opening necessary to bring about supply of the proper amount ofsteam to a radiator and remove the closure plug 23 of that particularopening or channel or the plugs of two or more channels the combinedareas of which are necessary to furnish the desired amount of steam.

In order that the selected open channel may be directed within theradiator as desired, it is preferable that the series of open;

ings or channels above mentioned, having corresponding series numbers asindlcated at 24 upon the outer end of the bushing and around its supplypipe reeeivingbore whereby when the bushing is inserted in a radiator itmay be turned until the selected open channel is directed up or downwithin the radiator or in whatever other direction may be desired.

It is obvious that when our improved bushing is once inserted, thesupply of steam is thereby regulated without danger of i change exceptby removal of the bushing,

- We claim:

1. A radiator bushing comprising a chambered body flanged at one end andexternally' threaded adjacent to said flange to screw within a receivingaperture of a radia tor, said body having a threaded supply pipereceiving bore centrally of its flanged end opening into its chamber,and having at its opposite ends' a series of graduated openings ofvarying sizes radiating from itschamber and each provided witharemovable closure, said bushing having at its first mentioned end aseries of distinguishing numerals opposite and corresponding to theopenings of said series of openings as described.

2. A radiator bushing com rising a chambered body flanged at one en andexternally threaded adjacent to said flange to screw within a receivingaperture of a radiator, said body having a threaded supply pipereceiving bore centrally of its flanged end opening into its chamber,and havin at its opposite ends a series of gradua ings of varying sizesradiating from its the wall of its inner opentures of graduated crosssection through its opposite end, opening into its chamber, and plugsforming detachable closures for said apertures.

4. A bushing comprising a hollow body externally threaded to screw intoa radiator opening, having at one end a threaded supply pipe receivingbore, and having at its opposite end a series of radiator supplyapertures with means to regulate the effective area of and supplythrough, said apertures.

5. A radiator bushing comprising a hol low externally threaded bodyhaving a threaded supply pipe receiving bore at its outer end and havingat its inner end a series of radiator supply apertures of varying crosssections, each aperture having a removable closure for the purposedescribed.

6. A supply bushing for steam radiators, comprising a hollow externallythreaded body adapted to be screwed into a radiator coil and having athreaded supply pipe receiving bore at its outer end, said bushinghaving a radiator supply aperture of pre-' determined area substantiallyreduced with respect to its body bore and opening through ortion in 'o ncommunication with the posed so that the inflow of steam through thebushing in use may be forcibly directed upwardly into a radiator coil,the inner end of the bushing being closed so as to prevent inflow to aradiator except through said nozzle forming aperture.

In testimony whereof we have affixed our signatures. i ALBERT B. HOLLEY.
